OUR VERDICT

For hikers who want something lighter than a full-blown, high alpine boot but more capable than an approach shoe, the Zionic NXT is a seriously compelling option. It won’t replace a more reinforced mountaineering boot in really sketchy terrain, but for fast-packing, long day hikes, and mixed trails it punches well above its weight.

Features Waterproof membrane (KEEN.DRY), mid-cut height, multi-directional lugs, contoured fit, lightweight PU midsole cushioning, mesh upper with overlays
Price £160

Pros

  • Light and very responsive feel for a waterproof mid.
  • Tremendous traction in varied terrain.
  • Supremely comfortable out of box with minimal break-in needed.
  • Waterproofing holds very solidly in moderate wet conditions.

Cons

  • Lighter build means less structural support under heavy load.
  • Durability in aggressive terrain is modest.
  • Not ideal for deep mud or sustained wet exposure from above.

WHAT I’M LOOKING FOR

I expect boots like this to: protect against wet underfoot, grip well on slick rocks and loose ground, handle repeated terrain abuse without falling apart, and feel good on my feet for hours without hotspots or soreness. If it also has a look than can work off-trail without looking like an IT teacher on Duke of Edinburgh, then that’s a bonus.

FIRST IMPRESSIONS

Out of the box, the Zionic NXT feels reassuringly light, true to its marketing. Fair enough. It doesn’t carry the heft of a stiff mountaineering boot, but it definitely doesn’t feel toy-soft either. The mesh upper with structural overlays gives a sense of tension and form: this is meant to move. The contoured-fit shape gives a snug but not too tight, performance-oriented shape; the mid cut is enough to offer ankle protection without over-restriction. The lacing hardware, tongue gusset, and waterproof membrane feel neatly integrated and well designed.

THE TEST

I put the Zionic NXT through a series of trails over wet rock, mixed scree, grass, light rivers/streams, long climbs, and transitions between trail and path across Yr Wydffa and the North Wales coast in a wet and cold mid-winter.

WHO IS THIS ITEM FOR?

This is a boot for fast hikers and day hikers who prefer a bit more elevation cushion plus those who want something waterproof but nimble. If your treks are heavy-load, technical, or very aggressive, you’ll want something stiffer with more support. But for many users who want a single boot for trail and moderate terrain, this is a candidate at the front of the pack.

WHAT STANDS OUT?

– Lightweight and best-in-class waterproofing because not many mids do both well at all tbh.
– Traction versatility because it handles slick rock, loose ground, wet patches like a charm.
– Comfort without any fuss whatsoever.

VALUE FOR MONEY

At £160, you’re not in the bargain bin, but you’re also not paying premium. For what you get – proper waterproof membrane, decent mid-height protection, solid outsole, lightweight design – it’s definitely fair value if this boot fits your style of hiking.

BASE BOTTOM LINE

The Keen Men’s Zionic NXT waterproof is a smart, capable mid-height hiking boot that bridges the gap between agility and protection. It won’t be your “go-anywhere” boot, but for many real-world hiking scenarios from wet trails, transition paths, to variable terrain, it delivers with aplomb.
